Specification of Letters Patent.

Application filed January 6, 1908. Serial No. 409,519.

To all whom it may concern:

Be it known that 1, ANDREW J. Burns, a citizen of the United States, residing at Sandusky, in the countyof Erie and State of Ohio, have invented certain new and useful Iin rovements in Receptacles for Holding Mol ten Glass; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willen'able others skilled in the art to which it'appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked Aahereon, which form a part of this specifica- ,tion. v i I This invention relates to new and useful improvements in pots for holding molten glass from which cylinders and hollow glass articles may be drawn. and consistsessentially in the provision of a ct made up of .two parts, so constructed that the bottom can be separated from the rim, whereby the bottom of the pot may be relieved of refuse glass adhering thereto, by the bottom being i Subjected to melting heat,

. The invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appiended claims.

, y invention is illustrated in the accompanying drawings, in which: 1

Figure 1 is avertical sectional view through a pot made in accordance with my invention, parts for raising and lowering the bottom part. being-shown in elevation. Fig. 2 is a view throughthe pot showing the bottom lowered, and Fig. 3 is a top plan view.

Reference now being had to the details of 40 the drawings by letter, A designates a casing for the pot which is chambered out as at A forming a heating chamber into which a seriesof pipes B lead for conveying gas to saidchamber, which is burned for the purpose of, keeping the glass in a molten state. f Ov designates a rim of the pot' which. is flanged and rests upon said casing, and D designates the movable bottom of the pot, Altheupper surface of which is inclined as at so D,-so constructed forthe purpose of allowing an accumulation of glass thereon to run off the marginal edge of said inclined surface "when the bottom is lowered and the glass thereon subjected to the action of the heat, thereby affording means whereby the bottom may be cleared of the refuse glass. It will benoted that the chambered portion of said casing has exit outlets F, whereby the refuse molten glass may make eXit'from the chamber as it falls from the inclined upper surface of the bottom. Said bottom I) is made preferably of clay and has an integral stem'D" which is hollow to receive an iron rod E which also passes through a shell H. Set

screws E are passed through said shell and adapted to hold. the same in an adjusted position upon the rod and set screws H are also mounted in the wall of an enlarged portion of the shell and. are designed to engage indentures formed in the outer surface of said stem, as shown clearly in Fig. 1 of the drawings. Said rod E is mounted in suitable guides K fastened to the cross pieces N, and O is a pin projecting from said rod. Q designates a lever pivotally mounted upon a pin Q and one end of said lever is slotted as at R for the reeeption of the pin 0. The opposite end of the lever is apertured and receives the threaded end of a screw 3 mounted in a threaded collar T fastened to any stationary object and the upper end of the screw S has an operating wheel S, whereby the screw may be turned for the purpose of raising or lowering the bottom of the pot.

The operation of my invention will be readily understood and is asfollows :When

the bottom is closed or assumes the position shown in Fig. 1 of the drawings, the potis in readiness to receive a ladle of molten glass which is poured therein and from which a cylinder is to be drawn. After the cylinder has been drawn, the operator by turning the screw S may causethe bottom of the-got to be lowered to the position shown in ig. 2 where'the refuse glass upon the upper inclined surface of said bottom may be melted and run off the edges thereof and make'exit through the openings F, thereby thoroughly cleaning the bottom after which the screw S may return to the bottom to its raised position in contact with the rim and in readiness for a repetition of the drawing of a cylinder.,

What I claim to be new is 1. A pot for holding molten glass from which hollow glass articles may be drawn which hollow glass articles may be drawn made up of a rim and a movable bottom, the upper surface of which is inclined over its entire upper surface, and means for raising and lowering said bottom, as set forth.

3. A pot for holding molten glass from which hollow glass articles may be drawn made up of a rim and a movable bottom, the upper surface of which is inclined over its entire upper surface, a rod upon which said bottom is adjustably held, and means for raising and lowering said rod, as set forth.

4. A pot for holding molten glass from g which hollow glass articles may be drawn made up of a rim and a movable bottom, the upper surface of which is inclined over its entire upper surface, a rod upon which said bottom is adjustably held, a pin projecting from said rod, a pivotal lever engaging said pin,

and means for tilting said rod, as set forth.

5. A pot for holding molten glass from which hollow glass articles may be drawn made up of a rim and. a movable bottom, the upper surface of which is inclined over its entire upper surface, a rod upon which said bottom. is adjustably held, a pin projecting from saidrod, a pivotal lever engaging said pin, a screw connected to one end of said lever, and a threaded collar through which said screw passes, as set forth.

6. A pot for holding molten glass from which hollow glass articles may be drawn made up of a rim and a movahle bottom, the

upper surface of which is inclined overits entire upper surface, said bottom having a hollow stem, a rod inserted in said stem, a shell fixed to said rod and engaging said stem, and means for raising and lowering the rod, as set forth.

7. A pot for holding molten glass from which hollow glass articles may be drawn made up of a rim and a movable bottom, the upper surface of which is inclined over its en tire upper surface, said bottom having a hollow stem, a rod inserted in said stem, a shell mounted upon said rod, means for holding the shell in an adjusted position upon the latter, the lower end of the stem seated in said, shell, screws carried by the shell and engaging said stem, and means for raising and lowering the rod, as set forth.

8. A pot for holding molten glass from which hollow glass articles may be drawn made up of a rim and a movable bottom, the

uppe surface of which is inclined over its entire upper surface, a chambered casing upon which said rim rests, the lower portion of said chamber having exit openings, heating pipes extending into said chamber, and means for raising and lowering the bottom, as set forth. In testimony whereof I hereunto aiilx my signature in the presence of two witnesses.
